On Oct. 28, 1971, the United Kingdom launched its first satellite. Here's why it mattered.
Two nearly identical materials have completely different chemical behavior. Research teams at the University of Vienna and TU Wien studied catalysts that use the energy of sunlight to produce ammonia. Surprisingly, when the three iron atoms that form tiny triangles in these catalysts are replac...
Macromolecular crowding can serve as a design tool for controlling the formation and organization of synthetic DNA droplets, a study from Science Tokyo reveals. Researchers investigated this strategy using DNA nanostars and polymeric crowding agents to mimic the crowded cellular environment. Th...
An international study investigating why wild tomatoes are more resistant to the tomato leafminer (Phthorimaea absoluta) than cultivated varieties revealed that the secret lies in the spatial structure of a plant defense molecule. The researchers mapped the biochemical origin of this difference ...
